Steering lamp structure based on flexible circuit board

Abstract

The invention relates to a steering lamp structure based on a flexible circuit board, wherein the flexible circuit board is arranged at the inner side, close the back side of a steering lamp, of a cover plate at the inner cavity of the lamp body of the steering lamp; the flexible circuit board is provided with a plurality of positioning holes; the cover plate is provided with positioning pins; each positioning pin corresponds to the corresponding positioning hole; the flexible circuit board is fixed through the matching between the positioning holes and the positioning pins; the top end of each positioning pin is provided with a sealed cover which is used for preventing the flexible circuit board from falling off; circuit elements are welded on the flexible circuit board; one end of the flexible circuit board is welded with an outgoing conducting line; the outgoing conducting line penetrates out through a small hole which is formed in a lamp housing of the steering lamp. The steering lamp structure based on the flexible circuit board has the advantages that the manufacture technology is simplified without reducing the luminous effect of the steering lamp, and meanwhile the production efficiency is also improved as long as the corresponding circuit elements are welded on the flexible circuit board, the flexible circuit board is arranged in the lamp body through the matching between the positioning holes and the positioning pins, and components, such as supporting strips, are unnecessary; moreover, the flexible circuit board has a good winding property, and the phenomena of disconnection and line falling can be avoided.

Description

technical field [0001] The invention relates to a turn signal lamp structure based on a flexible circuit board. Background technique [0002] Most of the existing automobile turning lights are mainly composed of lamp housings or lampshades, and internal light-emitting components; however, the light-emitting components currently used in turning lights have many defects in actual production and use. First of all, the structure of the bracket bar used in the light-emitting part plus the LED circuit board and the wire connection makes the whole part need to go through the fixed installation of the LED circuit board on the bracket bar, the circuit board on the card slot and the base during the production process. Weld the wires between them and connect the adjacent circuit boards on the base with dripping solder wire, and then embed this light-emitting component into the lamp housing or lampshade as a whole. Such a structure is relatively cumbersome in terms of manufacturing pro...

AI Technical Summary

Problems solved by technology

Such a structure is relatively cumbersome in terms of manufacturing process.

Secondly, the wires connected during use will fall off due to various reasons, causing the light-emitting diode to break and affect the luminous effect of the entire turn signal.

Moreover, the original support bar is very large in structure and takes up more space. At the same time, the volume of the light-emitting diode is also relatively large, and the lighting effect is also average.
